2. Read Discrete Inputs
3. Read Input Registers
4. Read Holding Registers
5. Write Single Coil
6. Write Single Holding Registers
7. Write Multiple Coils

This code can be configured by macros defined in mbap_conf.h and mbap_debug.h

Each function code can be enable/disable by macro defined in mbap_conf.h
Debug msg and warning can be controlled macros defined in mbap_debug.h

Modbus data should be intialised before using the stack. This should be done by passing
ModbusData_t structure into mbap_DataInit function.

Received query and length is passed into mbap_ProcessRequest function which gives response length
and copies response into response buffer.
